MELBOURNE, AUSTRALIA - APRIL 30: A protestor holds a banner of 23-year-old Iranian known as Omid, an Iranian refugee who set himself on fire at the Nauru detention centre and died in a Brisbane hospital, during a protest demanding that asylum seekers held in off shore detention to be brought to Australia at a rally in Melbourne, Australia on April 30, 2016. Protests have started after The Papua New Guinean Supreme Court ruled that the Australian-run detention centres on Manus Island were illegal and unconstitutional.
